Mini-Circuits TCD Surface-Mount Bidirectional Couplers

Mini-Circuits TCD Surface-Mount Bidirectional Couplers offer 10dB or 20dB nominal coupling, 0.2dB or 2dB typical mainline loss, and a power handling capability of up to 2W. This series includes two options. The TCD-10-23BDX+ features excellent flatness from 5MHz to 2250MHz, and the TopHat® design provides faster and more accurate pick-and-place assembly. The TCD-20-23BD+ coupler offers low mainline loss from 500MHz to 2000MHz and a robust and reliable design. Both types are built with core and wire construction mounted on a 0.16" x 0.15" x 0.22" base. Mini-Circuits TCD Surface-Mount Bidirectional Couplers feature 50Ω impedance and are ideal for cellular, UHF, and other applications.
